Figure 28. 15-Bit True-Color Mapping using R6–R0
and G7–G0
The part has two modes of operation for 15-bit True Color. In
the first mode, data is input to the device over the red, green
and blue channel (R7–R3, G7–G3 and B7–B3) and is internally
mapped to Locations 0 to 31 of the Look-Up Table (LUT)
according to Figure 27.
In the second mode, data is input to the device over just two of
the color ports, red and green (R7–R0 and G7–G0) and is inter-
nally mapped to LUT Locations 0 to 31 according to Figure 30.
(Note: Data on unused pixel inputs is ignored.)
There are three modes of operation for 8-bit Pseudo Color.
Each mode maps the input pixel data differently. Data can be
input into one of the three color channels, R7–R0 or G7–G0 or
B7–B0.
In 24-bit Palette Bypass Mode, the red, blue and green color
channels bypass the Pixel Mask and the Color Palette. Each 8-
bit color channel is mapped onto the 8 MSBs of the correspond-
ing 10-bit DAC input. The two LSBs on each DAC are zeros.
The Bypass Mode can be selected in two ways, by using CR27–
CR24 of Command Register 2 or on a pixel by pixel basis using
the PS inputs (ADV7160 only).
In 16-bit Palette Bypass Mode, the color channels bypass the
Pixel Mask and the Color Palette. The 8-bits of red pixel data
and 8-bits of green pixel data are mapped onto the 5 MSBs of
the red and blue DAC input and the 6 MSBs of the green DAC
input as shown in Figure 29. The remaining LSBs on each
DAC are zeros. The Bypass Mode can be selected in two ways,
by using CR27–CR24 of Command Register 2 or on a pixel by
pixel basis using the PS inputs (ADV7160 only).
